The query:
select events_events.id FROM events_events
left join events_event_types on events_events.eventType_id=
events_event_types.id
where events_event_types.severity=70
and events_events.cleared='f'
order by events_events.dateTime DESC
The main problem seems to be lack of a suitable index...
- Try creating an index on events_events( eventType_id, cleared )
- Or the other way around : events_events( cleared, eventType_id )
(depends on your other queries)
Please try both and report EXPLAIN ANALYZE.
